A Micro Switch is a small, very sensitive switch which requires minimal compression to activate. They are very common in home home equipment and switch panels with small buttons. They are usually cheap and have a protracted life meaning they'll perform for a long time - sometimes up to ten million cycles.

Because they are dependable and sensitive, micro switches are often used as a safety system. They are used to forestall doors from closing if one thing or someone is in the way in which and other applications comparable.

A unionwell micro switch reacts to surroundings modifications by opening and/or closing a set of switching contacts to control an appliance. When the micro switch senses movement from it’s surroundings, a plunger is pressed or released to open or close a circuit. The plunger actuator requires a certain amount of drive towards it to alter the contact mode, which is considered one of our customized choices!

Micro Switch Actuators

Each micro switch has a plunger actuator to change the contact mode, however many have a further actuator similar to a float or sail, to sense the setting change, corresponding to liquid level or air circulate. Unionwell offers many alternative actuator choices in addition to the essential plunger design:

  • Roller Actuator
  • Sail/Paddle Actuator
  • Leaf Actuator
  • Styrene Float Actuator
  • Whisker Actuator

Roller Actuator

A roller screw is a sort of screw drive that replaces the recirculating balls with threaded rollers. The ends of the rollers are toothed to mesh with geared rings at every end of the nut. The rollers each spin on their axes and orbit across the nut, in a planetary configuration. (This is why roller screws are additionally referred to as planetary roller screws.)

A roller screw replaces recirculating balls with threaded rollers.
The nut has an internal thread that matches the screw thread. The rollers are arranged in a planetary configuration and both each spin on their axes and orbit across the nut.
The ends of the rollers are toothed to mesh with geared rings at each end of the nut, guaranteeing that the rollers stay in good alignment, parallel to the axis of the screw and nut.

Sail/Paddle Actuator

Sail actuator proves air move with a contact output signal to a building automation system, digital air cleaner, humidifier or different methods. Typically mounted in a return air circulate duct where the sail will be in the direct path of an unobstructed air stream. When you add a sail, or paddle to the leaf the micro switch will sense air circulate and pressure

Leaf Actuator

A switch with a leaf lever that's rounded on the top and can be used as a easy roller lever switch.

The leaf switch may also be activated by the closing of an automated garage door. As the door touches the leaf, it triggers the switch to close off the motor and stop the motion. The leaf has a wider and larger surface area for contact in comparison with the whisker. It may be modified in it’s form and it holds its form in a number of use.

Styrene Float Actuator

Float switches provide an financial solution to monitoring the commonest liquid degree functions in tanks and different vessels. The Unionwell float switch is a snap action microswitch designed with a Stainless Steel leaf and a Styrene Float.

Whisker Actuator

Whisker switches are commonly used as a finding activate an assembly line or conveyor. If an item is misplaced and moves the whisker, the plunger is activated and the micro switch sends an alarm to the operator. Another widespread application allows vending machines to perform, the wire actuates the micro switch by the insertion of money and urgent of buttons to dispense the suitable merchandise into the drawer.
