Disclosed are a touch panel and a method of manufacturing the same. The touch panel includes a gas generation layer (110); a sensing electrode pattern (113) on the gas generation layer (110); a gas blocking layer (112) between the gas generation layer (110) and the sensing electrode pattern (113) to block a gas generated from the gas generation layer (110).

The invention relates to an arrangement (1) for an electric switching device such as a relay or a contactor, comprising two opposing contacts (3, 3') for performing the switching operation. In order to provide an arrangement for an electric switching device which effectively reduces or prevents the formation of conductive way paths for creepage currents and which is compact and easy to produce, it is intended according to the invention, that at least one of the contacts (3, 3') is surrounded laterally at least in parts by a barrier wall (7, 7').

Direct current switching apparatus having two arc extinguishing chambers each comprising a pair of spaced conductors providing cooperable arc runners divergent toward a row of nonferromagnetic splitter plates and a stationary contact conductively mounted on one conductor, the stationary contacts of respective chambers being mounted on respectively opposite conductors, corresponding conductors in respective chambers being conductively connected to each other and to power terminals of the apparatus, permanent magnets affixed against external surfaces of the housings of the arc chambers applying a magnetic field across the respective chamber for moving an arc within the chamber, ferromagnetic plates disposed around the arc chamber housings and the permanent magnets providing flux return paths to optimize and maximize the magnetic field, a movable contact extending into each chamber bridging the stationary contacts and movable by an electromagnetic actuator to separate the movable and stationary contacts, drawing an arc therebetween in each chamber, the arc in one chamber subsequently bridging the pair of conductors within that one chamber establishing a circuit comprising the arc between the conductors and the power terminals in shunt of the movable contact, thereby eliminating the arc in the other chamber, the bridging arc being driven into the respective splitter plates to be extinguished therein, interrupting the circuit. The magnetic fields are applied in opposite directions in the respective chambers for non-polarized operability of the apparatus. The magnetic fields are distorted within the splitter plate area of each chamber to drive and maintain an arc at a final stable arc position against a sidewall within the splitter plates, the wall thickness being increased at that position to withstand erosion. In a preferred embodiment the switching apparatus comprises a lightweight, compact, hermetically sealed contactor rated at 250 amp, 270 volts.

A switch device comprises a support member (4) having at least first and second stationary con­tacts (8a,12b) thereon. An armature (32) is mounted on the sup­port member by means of a body of elastomeric material (46) that is attached to both the support mem­ber and the armature. Deformation of the body of elastomeric material allows the armature to pivot relative to the support member between a first position in which electrically-conductive material (50a,50b) of the armature establishes electrically conductive connection between the stationary contacts and a second position in which the armature is spaced from at least one of the contacts. At least one permanent magnet (42a,42b) is carried by the armature. An electrically-driven switch actuator (20) is mounted stationarily relative to the support member and has first and second energization states. In the first energization state, magnetic material of the switch actuator is in magnetically-coupled relationship with the permanent magnet and a force is produced that causes the armature to assume a selected one of its first and second positions. In the second energization state, a force is produced that causes the armature to assume the other of its first and second positions.
