This panel mount Toggle Switch has built-in indicator lights so you know when the switch is on. They mount in a 20.2mm diameter hole and are rated up to 16A 12V. These SPST switches have three terminals, the two of which you would normally see plus one at the blue LED. Although these are for 12V, the LED only works on 5V.
This small On/Off/On Round Switch up to 10A at 125V AC can be mounted on a panel with a 20mm diameter hole. It will also look very elegant in your project.

A Pedal of Metal. This is the same type of Pedal you might find on a tattoo machine or as a damper pedal on an electric piano. The non-slip pad on the top and rubber bumpers on the bottom prevent the pedal from slipping out of place during use. If it opens, it's a simple switch and a big spring. This Pedal, however, has been described as "elegant and generous" and I think we have to agree.
Shield of relays for Arduino, with 2 channel mechanical relays and with 2 channel MOS switch , providing an easy way for applications low and high voltage control.
A Universal Relay Board Kit with 16 Relays and Connectors included! Transformer included. The 12V DC output can be used as a power supply for other kits. Each outlet can be equipped with a noise suppressor.
Relay, as its name implies, implements a relay function. The relay can be used as a switch operated electrically through the coil to mechanically operate a switch, where it is sometimes necessary to control a circuit of another voltage and current load through a separate low power signal, such as a digital signal emitted by a mircoprocessor. Up to 30V DC and 220V AC.
