91MCE18-S5B

Snap Action, Limit Switches

The 91MCE18-S5B is a snap action, limit switch that is designed for light to heavy duty applications. It is a heavy duty switch with a strong mechanical actuator and a long life, durable switch design. The switch is able to withstand extreme temperatures, dust and contaminants with its ingress protection rating of IP66.

The 91MCE18-S5B is constructed with a polyamide molded housing, stainless steel spring, gold plated electrical contacts and a snap action lever for reliable actuation. It also has a maximum temperature rating of +135°C and a dielectric strength of 1500V.

The working principle of the 91MCE18-S5B is similar to that of a push-button switch. When the switch is actuated, the lever is forced up, which causes the gold-plated electrical contacts inside the switch to make contact, enabling an electrical circuit. The contacts remain in contact as long as the lever is held up by external force.

The 91MCE18-S5B is commonly used in automotive, HVAC and white goods industries. It is well suited to applications where momentary electrical switches with high reliability are required, such as lights, fuel pumps, and vent fans. The switch is also common in the manufacturing industry where it is used for controlling material handling equipment, process controls, and automated machine systems.

Overall, the 91MCE18-S5B is an economical and reliable solution for a variety of applications where control and actuation are required. The switch offers long life and consistent operation, excellent ingress protection, and a relatively simple installation with quick turn-on and turn-off times.
