Comus Comus

Comus is a leading global manufacturer of reed switches, proximity switches, tilt and tip switches and vibration sensors – electronic components which are all widely used in electrical circuits.

Reed switches are commonly used in systems where low current is available and operate by virtue of a magnetic field. The contacts of a reed switch are made of metal which are enclosed in a glass tube envelope and separated when the switch is open. You will find reed switches like those made by Comus in devices such as burglar and security alarms, where the reed switch is activated by the movement of the door. Reed switches were also traditionally used extensively in computer keyboards, or other applications where a low current is required and the contacts of the switch needs to be protected from the environment.
