Mini Toggle Switches That Actually Fit — MTS, SMTS, E-TEN, PS-102 & DS438 Series

Whether you're wiring a custom control panel, retrofitting a vintage amplifier, or building a DIY electronics project, finding a mini toggle switch that matches your exact pin count, position, and actuator style can be frustrating. This listing solves that by bringing together the most widely used mini toggle switch families — MTS, SMTS, E-TEN, PS-102, and DS438 series — in one place, so hobbyists, technicians, and makers can get exactly what they need without hunting across multiple suppliers.

Each set includes the quantity you select (available from 1 to 60 pieces per order) of your chosen switch type. The MTS and SMTS series feature a compact metal body with a threaded bushing (typically M6) for panel mounting, available in 2-pin (SPST), 3-pin (SPDT), and 6-pin (DPDT) configurations in 2-position or 3-position (on/off/on) action. E-TEN series switches share a similar form factor with 2 to 6 pins. PS-102 variants come with colored caps (red, black, yellow, blue, white) for quick visual identification. DS438 series switches use spade terminals with pin widths of 4.8mm (≈3/16″) or 6.3mm (≈1/4″). Waterproof cap accessories in 6mm and 12mm sizes are also available as separate variants. Black Bakelite-body versions of select E-TEN models are included for applications requiring non-metallic housings.

Typical use cases include DIY control panels and instrument clusters, automotive and marine accessory switching (12V/24V DC), guitar amp channel switching and effects loop bypass, industrial machine control prototyping, and home automation relay trigger circuits — all scenarios where a reliable mini toggle switch with a known part number is essential.

🔌 Compatibility Note: Pin width, thread size, and panel cutout diameter vary by series. MTS/SMTS/E-TEN models typically require a ~6mm panel hole; DS438 spade-terminal models do not require a threaded bushing. Select your variant carefully and confirm dimensions before drilling or soldering.

✅ Key Features of These Mini Toggle Switches

🔢Wide Series Coverage — Includes MTS, SMTS, E-TEN, PS-102, and DS438 families in a single listing, covering 2-pin SPST, 3-pin SPDT, and 6-pin DPDT configurations for single and dual-circuit control.
⚡Latching & Momentary Options — Choose maintained (latching) switches for power control or momentary-action variants for signal and trigger applications; double-sided momentary models (MTS-123, MTS-223, E-TEN123, E-TEN223) are included.
🎨Color-Coded Cap Variants — PS-102 series switches are available with red, black, yellow, blue, and white actuator caps, making it straightforward to color-code functions on multi-switch panels.
🏗️Metal & Bakelite Body Options — Standard metal-body switches suit most panel applications; Black Bakelite-body E-TEN variants provide electrical insulation and are suited for non-grounded enclosures.
💧Waterproof Cap Accessories Included — 6mm and 12mm silicone waterproof caps are available as variants, adding splash resistance to compatible switches without requiring a separate order.
📦Flexible Quantity Tiers — Order from 1 piece up to 60 pieces per variant, with per-unit cost decreasing at higher quantities — practical for both one-off repairs and small-batch production runs.

❓ Frequently Asked Questions

How do I choose the right toggle switch size and pin count?

Match the pin count to your circuit: 2-pin (SPST) for simple on/off, 3-pin (SPDT) for on/off/on or on/off, 6-pin (DPDT) for dual-circuit control. For panel cutout, most mini toggle switches in this series require a hole of approximately 6mm (≈1/4″) diameter. Confirm the exact spec in the variant description before ordering.

What is the difference between momentary and latching toggle switches?

A latching (maintained) switch stays in position after you release it — ideal for power on/off controls. A momentary switch returns to its default position when released — typically used for signaling, horn buttons, or reset functions. Variants labeled "Momentary" in this listing are momentary-action; all others are latching.

What current and voltage ratings do these mini toggle switches support?

MTS and SMTS series mini toggle switches are generally rated for 6A at 125VAC or 3A at 250VAC. E-TEN series switches are typically rated 6A/125VAC. DS438 series are generally rated 10A/125VAC or 6A/250VAC. Always verify the exact rating on the datasheet for your chosen variant before use in high-current applications.

Are these toggle switches waterproof or suitable for outdoor use?

Standard MTS, SMTS, E-TEN, and PS-102 variants are not inherently waterproof. However, this listing includes dedicated waterproof cap accessories (6mm and 12mm caps) that can be fitted over compatible switches to provide splash resistance. For fully outdoor or submersion-rated applications, additional sealing measures are recommended.

What thread standard do these toggle switches use for panel mounting?

Mini toggle switches in the MTS and SMTS series typically use a metric M6 threaded bushing for panel mounting. E-TEN series switches generally use a similar M6 or equivalent thread. The DS438 series uses a standard spade-terminal design without a threaded bushing. Confirm the exact mounting spec for your chosen variant before drilling your panel.

How do I wire a 3-position (on/off/on) toggle switch?

For a 3-pin SPDT on/off/on switch: connect your common wire to the center pin, and your two load wires to the outer pins. In the center (off) position, neither load is energized. For a 6-pin DPDT version, the same logic applies to both poles simultaneously, allowing you to control two independent circuits with one switch.

Can I use these switches in automotive or 12V DC applications?

Yes, mini toggle switches in the MTS, SMTS, and E-TEN series are commonly used in 12V and 24V DC automotive and marine applications. The DC current rating is generally higher than the AC rating — typically up to 15A at 12VDC for MTS series. Verify the DC rating for your specific variant before installation.
