Abstract: A composition for treating pain, which contains dibucaine, a pharmaceutically acceptable salt of salicylic acid, calcium bromide, and antiphlogistic steroid(s) as active ingredients; and a method for reducing pain, which comprises injecting said composition into the location of pain. Further, the present invention provides a composition containing antiphlogistic steroid as an active ingredient, which is for reinforcing pain relief action of a composition containing dibucaine, a pharmaceutically acceptable salt of salicylic acid, and calcium bromide; and a novel use of antiphlogistic steroid in the treatment of pain.

Abstract: An on-off switch comprising a contact element of conductive elastomeric material for establishing a current path between a plurality of terminals, and an actuating member for imparting a compressing force to the contact element. When the actuating member is manipulated to compress the contact element, the contact element is rendered electrically conductive to electrically connect the terminals with each other thereby turning on the switch.

Abstract: A switching apparatus in which at least one pair of contact electrodes is printed on an insulator base fixed to a switch casing, and a contact element of conductive elastomeric material is disposed at a suitable position opposite to these contact electrodes to be compressed by a compressing force imparted by a pressure imparting member. The switch is turned on when the contact element is compressed and turned off when the contact element is not compressed.

Abstract: An on-off switch comprising a contact element of conductive elastomeric material for establishing a current path between a pair of terminals, a movable member for imparting a compressing force to the contact element, and an actuator for actuating the movable member. When the movable member is actuated by the actuator to compress the contact element, the contact element is rendered electrically conductive to electrically connect the terminals with each other thereby turning on the switch.
