OVERVIEW
The Model 5550 Mechanical Vibration
Switch offers basic protection against gross
changes in structural seismic acceleration.
Its operating mechanism is purely mechani-
cal and consists of a tension spring attached
to a pivoting plate on an over-center
fulcrum – magnets are not employed.
Normally, this plate is in an untripped posi-
tion. However, in the presence of sufficient
seismic acceleration (whether vibratory or
impact), the trip plate will pivot beyond this
over-center position, snapping to a stable
tripped position where it contacts an inter-
nal microswitch relay, changing the state

    NOTE: If the machine is restarted immediately after a shutdown, the lockout period will be shortened because the thermistor will be hot. An increase in the ambient temperature will also shorten the lockout period.
