Johnson Controls M9300-2 External Auxiliary Switch Kit 2-SPDT

The Johnson Controls M9300-2 External Auxiliary Switch has many control options. This kit consists of two Single Pole Double Throw (SPDT) switches that are housed in a durable, high impact plastic housing. SPDT switches can be used as ON/OFF switch or to switch electrical signal between two circuits. The M9300-2 kit enables the users to incorporate these features in their existing HVAC system. For instance, an SPDT switch could be wired to turn on an alarm light if a pressure sensor is activated, or to switch on an auxiliary heater element if the conditions are right. The M9300-2 is designed to operate under a wide temperature of -40°F to 158°F conditions and is right for most HVAC applications.
