Sometimes, the simplest option is the best. And in terms of switches, single-pole toggle switch is about as simple as you can get.

It’s no surprise that the design has lasted over 100 years. Perfect for on-off switching, the toggle switch was first invented in 1917.

It’s simple, easy to read, and can make a very satisfying ‘snap’!

From its most recognised use - switching on and off a light - through to use in industry and audio applications, the toggle switch is a real workhorse of a switch.

Manually actuated by a mechanical lever, handle, or rocking mechanism, the toggle mechanism works via a spring. The switch actuator does not control the contacts directly, but turning it gradually stretches the spring, which drives the contacts very quickly as the mechanism passes the centre.

The toggle was first invented by William J. Newton in 1917 - before this, lights were turned on by twisting a key in the bulb socket. Homeowners were still quite slow to take up this new technology, however, as it meant installing wires around their walls. 

It’s a very reliable design, and despite increasing use of ‘quiet switch’ mechanisms, the toggle switch is still a strong choice. It also takes up very little room, so can be housed in large panels controlling many switches. 

The simple up and down positions make toggle switches very easy to read and organise, and when many are installed on a control panel with light indicators they are a clear and simple way of keeping track of many machines.

Taking it right back to basics is the Marquardt Series 0100 - a long-lasting, durable and powerful toggle switch with 50 000 mechanical switching cycles.

For a three-pole switch - such as for use as an engine circuit breaker - the Marquartd 0350 offers IP40 sealing, to protect from water damage.  

Nexus offers a range of toggle switches from OTTO and Marquardt, and a specialised Zago toggle switch for hostile environments.
