Abstract

540,040. Switch contacts. IGRANIC ELECTRIC CO., Ltd. April 22, 1940, No. 6660/41. Convention date, June 9, 1939. Divided out of 540,338. [Class 38 (v)] A self-aligning contact which is readily detachable from its support 18 comprises a shoe 25 with extending arms 26, which engage a neck in the support 18, and wider portions 27 with bent-over ends 28 which are engaged by a blade spring 29. To detach the contact the shoe is moved against the action of the spring 29 till the wide portions 27 are opposite the neck. The shoe is then slipped off the support 18. The support 18 has a ridge 30 about which the shoe can pivot. The contact is shown applied to a switch of the kind described in Specification 540,338.
