The disclosure provides a flexible pressure switch. A flexible electrode region and a flexible non-electrode region are formed on a flexible printed circuit board at the bottom layer of the flexible pressure switch, two flexible electrodes separated from each other are arranged in the flexible electrode region, a conductive elastic composite body is adhered to and located on the flexible non-electrode region through an elastic adhesion layer, a pressure contact cavity region directly facing the flexible electrode region is formed on the conductive elastic composite body, and an upper surface of the inner wall of the pressure contact cavity region can contact the two flexible electrodes simultaneously or successively so as to switch on the circuit when being pressed. The flexible pressure switch is simple in fabrication process, low in cost, stable in performance and suitable for mass production.

Disclosed is a microswitch that allows the setting of the microswitch to be detected. The microswitch includes a conducting element movable along a surface that includes at least one conducting track that is contacted by the movable conducting element. Actuating the microswitch moves the movable conducting element along the surface resulting in electrically connecting or disconnecting two electrical tracks and causing electrical switching. In addition, the contact surfaces electrically connected by the conducting element may have different electrically conductive regions such that moving the connected surfaces changes the electrical resistances. Different switch positions can be determined by measuring resistance.

A switch has a base comprising a flat circular recess formed on an upper surface thereof, a fixed contact disposed in an inner surface of the flat circular recess, a spring body that has a bellows shape in which a reference form unit is repetitively formed, the spring body being annularly disposed in the flat circular recess of the base, an operating body that has a turning unit fitted turnably in the flat circular recess of the base, and an operating projection provided in an inward surface of the turning unit. When the operating body is turned, the operating projection presses an end portion of the spring body to compress the spring body, which allows a contact to be switched.

A UPS system and mechanical switching arrangement therefor that is driven by an electromechanical actuator when a fault condition is detected thereby opening or closing a switch of the switching arrangement in response thereto within 8 milliseconds, preferably within 4 milliseconds, and more preferably within 2 milliseconds of a fault condition being detected. The UPS system has one switching arrangement for controlling current flow through a utility power path that is switched by an electromechanical actuator and another switching arrangement for controlling that is switched by an electromechanical actuator through an inverter power path that supplies an output-connected load with electrical power should a fault condition occur. The switching arrangements can be driven by a common electromechanical actuator or independent driven by separate electromechanical actuators enabling programmability of a plurality of different UPS system operating modes.
