ESSEN Series MV is a 2 circuit double break snap action Micro switch suitable for use in all applications demanding accurate control. Micro switch has 1 NO + 1NC contacts with form Z arrangement.
Double break action of the moving contact assembly breaks the circuit at two points resulting in low dissipation of arc and heat energy in the switch.
Snap action is achieved through spring controlled pivoted mechanism. Rapid changeover of contacts ensures reliable bi-stability, which results in long mechanical life.
These micro switches are available with straight terminals as well as with PC right angle terminals. Contacts are either silver alloy or silver alloy gold plated. Mounting is with the help of M2.2 screws.
Micro switch is actuated through integral plastic knob. The optional auxiliary actuators are available either in plain or roller lever.
