Rocker switches are devices that provide a selectable connection between two terminals through an operating handle or lever. Commonly used types of switches include latching, paddle, miniature, illuminated, and subminiature switches, among others. The 7107J1ZBE2 is one such device; a single-pole, double-throw (SPDT) rocker switch. The type of switch is appropriate for a variety of applications requiring a choice between multiple options, such as for ground and logic signals, and for toggling between on and off functions.

7107J1ZBE2 Description and Application Field

The 7107J1ZBE2 is a single-pole double-throw (SPDT) switch with a mounting hole of 12.7 millimeters in diameter. The switch features two circuits that provide an alternating connection between two terminal points when the handle is flipped up or down. The SPDT type of switch allows the manipulation of two circuits with a single switch component. The 7107J1ZBE2 also features a column tip to make latching the switch more straightforward and efficient. The switch has a maximum current handling capacity of 0.1 Amps and a maximum voltage rating of 30 VDC.

Various applications can benefit from the use of this SPDT rocker switch. Among them are electric appliances for home use such as electric irons and stoves, medical and laboratory equipment, printers and other electric peripherals such as USB hubs, and communications equipment such as telephone switching systems. The 7107J1ZBE2 is also used for electronic control systems in cars, machines, and electronic toys.

7107J1ZBE2 Working Principle

The first step in understanding the working principle of a rocker switch is to familiarize oneself with the contact mechanism inside the switch. The 7107J1ZBE2 has a single set of contacts, as is typical of SPDT switches, that are actuated by a double-pole, dual-throw lever. When the lever is pushed clockwise, it moves a contact away from the common terminal and opens the circuit connecting the two terminals. When the lever is pushed counter-clockwise, the opposite contact is moved away from the common terminal and the connecting circuit is opened again.

The connection between the two terminals is maintained when the lever is in the middle position, and is broken when the lever is actuated in either direction. Thus, the lever can only take two positions, whether connected or disconnected. When connected, the switch creates a closed circuit between the two terminals and when disconnected, the switch breaks the circuit.

The 7107J1ZBE2 also functions as a latching switch. This means that the switch stays in whatever position it is in until the lever is moved to a different position, when it will remain in the new position until the lever is moved again. This is ideal for applications that require the user to switch between multiple connected states, as the switch will stay in whichever state the lever was last placed in.

Conclusion

The 7107J1ZBE2 is a single-pole double-throw (SPDT) rocker switch, with a 12.7 mm mounting hole and a current handling capability of 0.1 Amps with a maximum voltage rating of 30 VDC. It is commonly used for electric appliances for home use, medical and laboratory equipment, printers and other peripherals will as USB hubs, and communications systems such as telephone switching. The working principle of this switch is that it maintains a closed circuit between two terminals when the lever is in the middle position, and breaks the connection when the lever is moved in either direction. It is also a latching switch, meaning that it maintains the current position until the lever is moved to switch between two or more states.
