MTLS-10A
The MTLS-10A is a weatherproof and explosion-proof housed magnetically-actuated electric switch designed for chamber exterior mounting on a Mange-Trac or Magne-Trac Plus magnetic level indicator having a magnetic float that rides a liquid level. The MTLS-10A provides electrical current switching via two isolation single pull double throw (SPDT) normally open or normally closed contacts and is configured for double pole double throw (DPDT) operation such that two separate devices can be controlled with a single switch within the switch rating. The switch is a latching, bi-stable design that when actuated by the passing MLI float, the switch contacts remain in the actuated position until the float, traveling in the opposite direction, passes back by the switch. The switch is well suited for sending high or low level alarm signals and operating pump control relays. Switch action is break before make.
