Clearance - final five. These are new, unused switches, and our 12 month warranty still applies. We won't be restocking this model. For a mini toggle that stays put in all three positions, see our MTS-103 toggle switch.

This mini toggle switch stays on one way and springs back the other. Flick the lever towards ON and it stays there. In the middle it is off. Push it towards (ON) and it connects only while you hold it, then springs back to off when you let go. So one lever gives you run in one direction and a short jog or reset pulse in the other.

It is an E-Switch 100SP5 with three flat PCB pins, so it solders straight into a circuit board with the lever through a 6.35mm panel hole. It switches up to 5A at 28VDC or 120VAC, and 2A at 250VAC, so use the 2A figure on New Zealand mains. The thread is imperial 1/4-40, and the nut, lockwasher and locking ring come fitted.

Wiring & getting started

  1. Lay out the board

    Give it three 1.85mm holes in a straight row, 4.7mm apart. The pins are flat blades 1.27mm wide, so they won't push into a breadboard or the 1mm holes of 2.54mm stripboard. For those, solder a short wire to each pin.

  2. Solder the pins

    The middle pin is common, so your supply or signal goes there. The lever joins the middle pin to the outer pin on the opposite side from where it points. Lever towards ON joins the middle pin to the pin at the (ON) end. Lever towards (ON) joins it to the pin at the ON end. Solder each pin quickly and let it cool before the next.

  3. Mount it in the panel

    Drill a 6.35mm (1/4 inch) hole. To stop the switch turning, drill a 2.4mm hole 6.1mm from the centre for the tab on the locking ring. Fit the locking ring behind the panel with its tab in that hole, then the lockwasher and nut on the front. Tighten gently, no more than about 0.5 Nm. An M6 nut does not fit this thread, so keep the one supplied.

  4. Check it works

    Use a meter on continuity before powering up. Lever towards ON: the middle pin connects to one outer pin and the lever stays put. Lever in the middle: nothing connects. Lever towards (ON): the middle pin connects to the other outer pin, and the lever springs back when you let go.

Note: The pins are bare metal. On 230V mains, keep the load to 2A, turn the power off before working on it, switch the active wire and mount the board in an enclosure. If you are not confident with mains wiring, have a qualified person fit it.

Frequently Asked Questions

Answers to the questions buyers ask most.

Why is this on clearance?
These are five new, unused switches, and our 12 month warranty still applies. We won't restock this model. For a mini toggle that stays put in all three positions, see the MTS-103 toggle switch.
Is there any warranty on a clearance item?
Yes. It has the same 12 month warranty as our regular stock, and your rights under the Consumer Guarantees Act are not affected by the clearance price.
Which way is the momentary side?
The side printed (ON) on the case. Push the lever that way and it connects only while you hold it, then springs back to the middle. The side printed ON stays on until you flick it back.
How do I wire the three pins?
The middle pin is common. The lever joins it to the outer pin on the opposite side from where the lever points. Only one side connects at a time, so the switch can't feed the ON side and the momentary side together.
Can I use it on 230V mains?
Yes, up to 2A on a resistive load such as a small heater or lamp, which is about 460W at 230V. The 5A figure on the case is for 120V supplies. For a motor or anything with a big start-up surge, use this switch to drive a relay.
How much can it switch on 12V or 24V?
Up to 5A on a resistive load, which is about 60W at 12V or 120W at 24V. For a motor or solenoid with a big start-up surge, use the switch to drive a relay.
Will it fit a breadboard or stripboard?
Not directly. The pins are flat blades 1.27mm wide and 4.7mm apart, made for 1.85mm holes in a circuit board. For a breadboard or 2.54mm stripboard, solder a short wire to each pin.
Can I read it with an Arduino or ESP32?
Yes. Connect the middle pin to GND and each outer pin to its own input set to INPUT_PULLUP. Each input reads LOW while its side is switched on, and both read HIGH with the lever in the middle.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
