POWERTOOL COMPONENTS FOR ANGLE GRINDER 2013
Tough Performance
Higher Value
Small Angle Grinder (SAG)
The power tool market is looking for non-teasible solutions
for all kinds of AC tools, and is expecting switches to carry
ever higher currents, lasting longer, keeping the existing
sizes and ergonomics, and at the same time expecting
switch suppliers to get this done with simple and robust
mechanism.
As the leading switch provider Defond is constantly looking
for challenges and getting into the higher level of angle
grinder switches.
As moving along the power scale, it begins with the
small angle grinder (500W to below 1000W class). This is
a highly competitve market without compromising switch
performance nor its reliability. Our patented non-teasible
mechanism of the new generation EPX switch (successor
of current DPX) has rated to 12(12)A 127Vac and 8(8)A
EPX
Features
- Single and double pole versions available
- Rating from 6A 127Vac up to 12A 127Vac
- Momentary ON
- Full dust protection on the actuator prevents sticking
- Internal fail-safe contact mechanism for longer life and reliability
- Anti-tease contact system (Patented)
- Optional integrated holder for common size capacitors
- Bi-stable
250Vac 5E4. It also has lower rated versions and different
configuration such as SPST, DPST for various applications.

Medium Angle Grinder (MAG)
One level up the power scale of angle grinder be the
medium angle grinder (between 1200W to 1800W class).
Thanks for the patented non-teasible mechanism, the
new generation, FPC switch (successor to existing APB/
FPB), is suitable for rated up to 15R(15)A 127Vac 5E4 and
10(10)A 250Vac 5E4 while keeping the same external dimensions and operating travels.

Large Angle Grinder (LAG)
Further up is the large angle grinder (over 2000W), the
market is looking for safe, flexible solution with extra valueadds; products are demanding switch and modules to
tackle zero voltage protection, soft start function and/or
over-loading protections under severe conditions.
Defond is providing the flexibility to our customer to choose
among different solutions. Our overhang switches like CGK
series with stand-by terminals can provide power to the
external modules, and customers can have maximum
flexibility on the circuitry design and mechanical fitting.
CGK
Features
On the other hand, some customers are looking for neater
and simpler solutions. Defond has the all-in-one solution:
the BGY switch. Just specify the necessary features for
customizing protections and functions with the switch.
- Dust tight design for rough environmental conditions
- Patented double snap action contacts for long trouble free
operation
- High rating, up to 12(12)A 250 Vac
- Lock-on, lock-off, or no lock options
- Optional surpression capacitor
- Interchangeable with most common sizes and type on the
market
- Standard and customized Trigger Options

LAG electronics (NVR)
New safety regulations is asking for more intelligence in the
AC tools: zero-voltage protection, soft start, over-loading
protections, and more. Defond is making these PCBA modules
for all the major brands and developed a complete series of
know-how from design to testing, and is well suited as a total
solution provider to tackle the task of making an even smarter
AC tool under different loading and working conditions.
- Restart protection to cut off tools when the power supply is
interrupted
- Intergraded E- switch

Electronic Modules
This “electronization” of AC tools starts at the large angle
grinder and some higher-end products, but is gradually
spreading down to the medium/small grinders among
premium brands. Smaller push button switches are
gradually docking with different customized PCBAs for
increasingly diversified functionalities like variable speed
control, soft starts and over load protection.
Please contact Defond for switch/PCBA module solutions
on your grinder products!
NVR
NVR is a standard AC control module featuring the no-volt
release function. This function prevents a tool from being started
in locked position after a power failure or after unplugging when
locked thus avoiding a potentially harmful situation.
Beside the NVR function the module also has feature like soft
start, overload protection and constant speed control. Beside
this standard module Defond can offer customized modules
according to customer specifications.
Features
- No volt release (NVR)
- Soft start
- Overload protection
- Constant speed control
- Optional customized
