• Magnetic spring contact switches are available as a factory installed option on 40-400 Series and 40-410 Series
• An excellent choice when an accurate pressure switch is required in addition to a reliable pressure gauge
• Fully adjustable by the user
• These switches are actuated by the pressure gauge pointer to provide accurate field adjustment
• A removable adjustment key makes them tamper-proof
• They operate with an extremely broad power supply, AC or DC up to 250V max. (30W 50 VA), allowing them to be used virtually anywhere in the world in addition to very remote applications with only DC battery pack power available
• Standard units consist of (2) two magnetic spring switches; either one or both switches may be used:
• Switch (1) one is normally closed
• Switch (2) two is normally open with operation referenced on clockwise pointer motion
• The lowest full scale pressure range this switch may be used on is 0 psi to 60 psi because of the increased load on the pointer and Bourdon tube
• A mating 4-pin connector with 5' of 4-wire and color coded shielded cable is standard
