What is mini limit switch?
A small limit switch is a mini switch that can be
mounted on a relatively stationary object (such
as a fixed frame, door frame, etc., referred to
as a stationary object) or on a moving object
(such as a traveling car, door, etc., referred to
as an animal). When the animal is close to the
static object, the linkage of the switch drives
the contact of the switch, causing the control
circuit to close the contact to break or break
the contact to close. By the switch contact open,
close the state of the change control circuit.
And limit switches are actually the most common
sensing device in industrial control, providing
an electrical signal when an object physically
touches and moves an actuator. Due to their easy
installation, reliability and rugged design, they
are suitable for a wide range of applications and
harsh environments. Limit switches are available
in a variety of configurations, such as rollers,
plungers, etc., and we can make them to your
specifications. Contact us!
