PURPOSE: To provide a switch mechanism having a high reliability for a long period by forming a movable contact in a V-letter form to be engaged with two immovable terminals for bridging a gap between the terminals.
CONSTITUTION: A movable contact, that is a short-circuitting bar 1, is a V-shaped element of gold-plated silver alloy, and the short-circuitting bar 1 is applied to a plate spring 3. The plate spring 3 is a flat spring supported between two support posts 16, and both ends 3A of it are freely movable. In a normal switch-opened condition, the plate spring 3 is bent in such directions that both its center part and the short-circuitting bar 1 get apart from immovable contacts 10, 12 respectively connected to terminals 11, 13. A compression spring 4 compressed between the bent plate spring 3 and a support bracket 5. The plate spring 3 is held in the bent condition, and the spring 4 is held in a condition compressed by length of a stopper wire 2 comprising Ni-Cr-Al. This wire 2 is wound around a ceramic spool 6 installed on the movable contact 1 through the compression spring 4, and both ends of it are installed on contact terminals 7, 8.

An overload relay is provided for electrical equipment, such as a motor. The overload relay includes a set of electrical contacts, a trip mechanism and a single-arm, a set of monolithic compliant mechanism actuators. The trip mechanism has a normal position and a tripped position. The normal position allows electrical connection between the electrical contacts, and the tripped position interrupts electrical connection between the electrical contacts in response to detection of a high current condition. The single-arm actuator is formed of an electrically conductive material, and includes a compliant hinge and a single bar connected to the hinge. The single bar is electrically coupled to the line contact or the load contact. Under the high current condition, one of first and second ends of the single bar deflects relative to the compliant hinge to cause the trip mechanism to move into the tripped position. |

A separated MEMS thermal actuator is disclosed which is largely insensitive to creep in the cantilevered beams of the thermal actuator. In the separated MEMS thermal actuator, a inlaid cantilevered drive beam formed in the same plane, but separated from a passive beam by a small gap. Because the inlaid cantilevered drive beam and the passive beam are not directly coupled, any changes in the quiescent position of the inlaid cantilevered drive beam may not be transmitted to the passive beam, if the magnitude of the changes are less than the size of the gap. |

A MEMS hysteretic thermal device may have a cantilevered beam which bends about one or more points in at least two substantially different directions. In one exemplary embodiment, the MEMS hysteretic thermal device is made from a first segment coupled to an anchor point, and also coupled to a second segment by a joint. Heating two respective drive beams causes the first segment to bend in a direction substantially about the anchor point and the second segment to bend in a direction substantially about the joint. By cooling the first drive beam faster than the second drive beam, the motion of the MEMS thermal device may be hysteretic. The MEMS hysteretic thermal device may be used for example, as an electrical switch or as a valve or piston. |
