Comus International was founded in June 1978 by Robert P. Romano.

Comus International started out as a manufacturer of glass mercury tilt-switches for residential and commercial thermostats. Immediate success and rapid growth led to new product development and soon the metal mercury switch and, ultimately, the patented non-mercury switch were designed and offered to the market which led to further success.

Today, Comus International is a leading manufacturer of tilt and tip-over switches, motion/vibration sensors, reed switches, reed relays, solid state relays, proximity sensors, float switches and a wide variety of custom turnkey sensors. Success of our product growth and offering has been built with an excellent reputation for quality and service.

Comus has evolved into a world leader in the design, development and manufacture of a wide variety of sensors and sensor-related products. Applications are found in such diverse market segments as medical, automotive, white goods, alarm and security, and military/aerospace.

Our success through the past several decades is a combination of continual organic and acquisition growth, leading to the formation of the Comus Group of companies. Divisions include the following:
