SS Body Pressure Switch (longbody, NEMA 4)
P117LG
The P117LG NEMA 4 Stainless Steel Pressure Switches are the weather-proof, liquid-resistant version of the P117G. The NEMA 4 rating makes these rugged switches suitable for outside applications or in areas of condensing humidity. Unlike the P117G, the P117LG set point is factory set to customer specification and is non-adjustable.

Temperature Switch
T150D
The T150D Adjustable Stainless Steel Miniature Temperature Switches provide the end-user with a wide range of functionality without impacting durability. The T150 is designed for use up to 510°F but can withstand temperatures up to 800°F while still protecting the set point and life of the switch. The limit filled, saturated vapor sensor is in direct contact with the temperature-sensing outer shell producing fast response and accurate temperature control. The external setting scale provides full range adjustment and the external lock screw allows for easy adjustment of set point.
