Switch Types Mechanical, Magnetic Proximity, & Inductive Proximity Mechanical switches are activated by pressing a spring return lever, and have physical contacts plated with a noble metal such as silver or gold. When energized contact is made, a small arc or spark can be produced within the housing of the switch that is not completely sealed off from the atmosphere. Mechanical switches are passive devices that do not require external power to operate. 41 Series / 45 Series Code 0 Silver Plated Switches SPDT Gold Plated Switches SPDT 48 Series Silver Plated Switches SPDT Gold Plated...

Limit Switch Technical Brochure Max-Air Technology Inc. | Rotary Actuators & Valve Automation Solutions Inductive proximity switches are activated by the presence of a magnetic or ferritic target which disturbs the sensor’s own magnetic field. Inductive switches are “active” devices which require external power and are available in a variety of configurations. Inductive type switches are inherently “nonsparking” and usually operate on low voltage DC power, making them well suited for intrinsically safe applications. 41 Series / 45 Series / 48 Series Code A
