ELECTRIC SWITCHES MANUFACTURING

The switches are of high quality and are used in hot plates, coolers, washing machines, electric cooking ranges etc. Rotary Switches are to 5 Amps and 15Amps rating and are fitted with very fine quality contracts for long lasting. The contacts close or open.

The switches consist of Bakelite body except for the hot plate switch. The hot plate switch has a ceramic base to withstand high temperature. The switches have a 360° rotation. The switches are provided with a black or white knob with proper marking. Single hole fixing is provided by a threaded brush. The switch is secured by a single center fixing nut.

Electric  switches,  plugs, sockets, etc.  are  nothing  but electric fittings which are quite familiar to the people as it is found  in every home.  They can be manufactured  using  different major   raw  materials  e.g.  steel,  brass,   thermosetting   or thermoplastic  resins  However this report is  totally  based  on bakelite  powder or resin which is thermosetting type.   Bakelite powder  is also known as phenol formaldehyde resin.   also  other electrical  accessories  e.g.  plates,  lamps  holders,  may   be manufactured  from phenol formaldehyde resin and same  plant  and machineries  making the industry highly flexible and  profitable. Besides  electrical fittings radio cabinets, inks  stands,  table lamps, door and cabinets, handles, power relay components, camera shutters,  textile  bobbins  and other accessories  may  also  be manufactured with little or no change.
As  mentioned  earlier  though electrical  fittings  may  be manufactured  from  other  materials also it may  be  noted  that bakelite  electrical  fittings  are best  and  economical.   Also bakelite  is  bad  conductor of  electricity  making  them  shock resistant  which  may  be  there  is  case  of  metal  electrical fittings.
Electric  fittings  are manufactured in different  sizes  as required  by  the  customer.  They may be of two  or  three  pin. Three pin sockets and plugs have one major advantage over two pin one’s since they are earthed also.  Also various combinations are practiced in the 5-15 ampere range.  These combinations are (1) 5 amp. switches, sockets, Bell push & Flush type fuses (2) 15  amp. and  5-15  amps. combination etc. can imagine the scope  of  this industry.   To  make  it more clear due  to  the  development  in electric  production more industries will be installed, more  and more  electricity, as well as industrial purposes which  in  turn will require more fittings.
Most  of the bakelite electrical fittings consist essentially  of three parts.
i.   The bakelite or plastic body.
ii.  Metal inserts and screws, springs etc.
iii. Ceramic base.
A  switch is a device to cut the electric circuit  when  not desired. A general use switch is a switch intended for  use  in general  distribution  and  branched circuits.  It  is  rated  in amperes  and is capable of interrupting its rated current at  its rated voltage.
