MD switches have been designed for applications that require robust, long lasting switches, coupled with high accuracy and repeatability, in adverse conditions. 

By using appropriate capsules and wetted parts, MD series pressure switches can be used for thousands of applications. 

A wide choice of electrical elements including SPDT, DPDT, gold contacts make these switches ideal for a variety of critical applications. 

A wide scale, when opted for offers ease of setting, given the smaller least counts.
