Setup
Installation of the Imperial 1355 Micro Door Switch requires basic electrical knowledge. Always ensure that the power supply to the appliance or circuit is completely disconnected before beginning any installation work to prevent electrical shock or damage.
- Disconnect Power: Turn off the main power switch or unplug the appliance from the power source.
- Remove Old Switch (if applicable): Carefully disconnect wiring from the existing switch and remove it from its mounting location.
- Mount New Switch: Insert the threaded barrel of the new Imperial 1355 Micro Door Switch into the designated opening. Secure it firmly in place using the provided hexagonal mounting nuts. Ensure the switch is oriented correctly for proper plunger activation.
- Connect Wiring: Reconnect the electrical wiring to the terminals of the new switch according to the appliance's specific wiring diagram or the previous switch's configuration. The Imperial 1355 features Quick-connect terminals for ease of installation.

Operating Instructions
The Imperial 1355 Micro Door Switch operates automatically based on the position of its plunger. It is designed with a Normally Open (NO) contact type and an automatic operation mode.
- Normally Open (NO) Operation: In its resting state, when the plunger is extended (e.g., a door is open), the electrical circuit connected through the switch is open, meaning no current flows.
- Plunger Depressed: When the plunger is depressed (e.g., a door is closed and presses against the plunger), the internal contacts close, completing the electrical circuit and allowing current to flow.
- Automatic Control: The switch functions as a control mechanism, activating or deactivating a function (like a light, fan, or safety interlock) based on the physical state of the door or component it monitors.
Maintenance
To ensure the longevity and reliable performance of your Imperial 1355 Micro Door Switch, follow these simple maintenance guidelines:
- Regular Inspection: Periodically inspect the switch for any visible signs of wear, damage, cracks, or corrosion on the body, plunger, or terminals.
- Cleanliness: Keep the area around the switch clean and free from dust, dirt, grease, or any debris that could impede the plunger's movement or affect electrical connections. Use a dry, soft cloth for cleaning.
- Connection Check: Ensure that all electrical connections to the switch terminals remain tight and secure. Loose connections can lead to intermittent operation or overheating.
- Avoid Force: Do not apply excessive force or impact to the plunger or the switch body, as this can cause internal damage.
- Environmental Conditions: Ensure the switch is not exposed to conditions beyond its intended operating environment, such as extreme temperatures or excessive moisture, unless specifically rated for such conditions.
