Elma Electronic AG has introduced three new type 07 coded switches featuring modular configurability, reliability and long lasting performance.

Elma’s new type 07 coded switches (07 ML, 07 P and 07 P2T) offer additional on-off function, pushbutton function, and push/pull-to-turn safety functionality against unwanted turning.

Vasileios Angelopoulos, product manager for rotary switches explains that the new switches are ideally suited for use in high quality devices and applications in challenging environments such as transport and military as well as in harsh industrial environments.

07 ML multilayer coded switches with on-off feature

The coded switch 07 ML comes in addition to the scalable coded levels, with another level offering an on-off function featuring a significantly higher switching torque of 5.7 to 7 Ncm compared to the normal detent. Random switching on-off can be avoided reliably. Even complex functions are feasible with up to four separated coded levels. Typical applications include audio and brightness controls with on-off functions as well as controlling optional functions that can be activated.

07 P coded switches with pushbutton feature

The coded switch 07 P comes in addition to the scalable coded levels with a pushbutton function. With the various push forces available (3, 5, 6, 9, 12 or 15N), the switch can be customised to its relative environment. The low push force is made for fixed devices while higher push force is ideal for mobile devices that may be subject to strong disturbance forces such as vibration, blows or side acceleration. This switch type is mainly used in menu controls. Typical applications are communication and machine devices as well as cockpits.

07 P2T coded safety switches with push/pull-to-turn feature

The coded switch 07 P2T has, on top of the normal coded function, a mechanical safety mechanism that prevents completely random or accidental operation. Based on the optional finish, the switch can be either pushed up against (push-to-turn) or pulled against (pull-to-turn) in order to turn the switch. Typical applications are flight cockpits, communication and machine control devices with demanding safety requirements, and military target devices.
