A three-way switch associated with an entry point barrier may provide a security system with information regarding a position of the entry point barrier as it moves along a path of travel. As the entry point barrier moves, the three-way switch may come into proximity with an external object, and the three-way switch may indicate to the security system that a circuit associated with the three-way switch has been closed. The security system may determine that the entry point barrier is in a given position, and one or more security system policies associated with the given position may be activated.

A contact switch including a rail having slot with a first straight section and a second curved section, a toggle unit inside a housing, the toggle unit including an extension unit that slidably engages the slot and at least one contact, a contact unit in the housing including at least one contact, where the toggle unit moves in the housing such that the contacts on the toggle unit engage at least one contact on the stationary unit in the first straight section and the contacts disengage in the second curved section.

A switch assembly and method of using same comprises a switch assembly for operating a power take off unit on a lawn tractor, the switch assembly further includes a housing supporting a selectively locatable activation knob facilitated by an actuation assembly and an internal switch arrangement coupled to a printed circuit board within the housing. The internal switch arrangement comprises a microcontroller and switch for determining the relative position of the selectively locatable activation knob and provides a digital output signal for enabling or disabling a power take off unit based on the digital output signal.

A switch includes a pushbutton comprising an actuating portion, a first fixed contact element and a first movable contact element facing the first fixed contact element for establishing a first switching way. The first movable contact element may include a movable portion of a first elastically deformable conductive blade. The actuating portion may include a first cam which cooperates with a cam follower portion of the first blade to deform or relax the first blade for longitudinally moving the first movable contact element to come into contact, or out of contact, with the portion of the first fixed contact element, depending on the vertical position of the actuation member. A second fixed contact element and second movable contact may be similarly constructed to provide a second switching way.

The invention relates to a door contact switch, especially for a switchgear cabinet, having a switching piece, a baseplate and a switch housing accommodating the switching piece, the switch housing being movably mounted relative to the baseplate. At least one edge of the baseplate has at least one baseplate snap-in device and the switch housing has at least one switch housing snap-in device such that the baseplate can be locked with the switch housing in at least two different positions.

An appliance switch provides contacts protected within a housing that may fit coaxially within and behind a pushbutton of the switch. The pushbutton includes a rearwardly extending arm that actuates an operator extending from a rear edge of the switch as installed avoiding a water path into the contact assembly.

A household appliance includes a compartment, a door for closing the compartment, a non-movable part, and a door monitoring apparatus including a contact pair which has two contact parts. One of the two contact parts is arranged on the door and the other one of the two contact parts is arranged on the non-movable part of the household appliance.
