Magnetic Switch

Magnetic Switch Image

This magnetic proximity sensor is hermetically sealed, industrial grade and completely waterproof. Maximum gap is 0.25", so be careful when installing. If you use a larger magnet, such as the example shown elsewhere in this product section, the gap can increase substantially.

Two of these switches are required for our roll off roof controllers (one to sense roof open, one to sense roof closed).

These switches are light-weight and small(1" x 1"). Two of these are ideal to sense the At Park status of your telescope. When connected in series and used in the SafeLoop circuit, your roof will not move unless both switches are engaged by the small accompanying magnets.
